I recently purchased a Dell Inspiron 750, and I have been working on optimizing the graphics. I just got glx working, as evidenced by running glxgears. However, direct rendering is disabled and I do not know why. My Xorg.conf file indicates that it is loading dri and dri2. Here is my Xorg.conf:

I do see these two lines in my Xorg.0.log:
19031.971] (II) AIGLX: Screen 0 is not DRI2 capable
19031.971] (II) AIGLX: Screen 0 is not DRI capable
Here is a pastebin of my entire Xorg.0.log in the event that it might be helpful:
19031.782] X.Org X Server 1.9.3 Release Date: 2010-12-13 19031.783] X Pr - Pastebin.com](http://pastebin.com/fhPuJ6Xc)
I appreciate any help. Thanks.
